Explanation:

Non - polar covalent bonds occur between two atoms with the same electronegativity. In $O_2$, two oxygen atoms share electrons equally, forming a non - polar covalent bond. $NO_2$ and $CO$ have polar covalent bonds due to electronegativity differences between atoms. $NaCl$ is an ionic compound.

Answer:

1. $O_2$
